MILLING ATTACHMENT FOR SHAPR-BAMS.

Specification of Letters Patent.

Patented Jan. 11, 1916.

Application filed July 6, 1914. Serial No. 849,236.

To all 107mm may concern.' Y

, Be it known that I, HENRY E. MoR'roN, a citizen 0f the United States of America, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Milling Attachments for Shaper-Rams, of which the following is a specification, reference being had therein tothe accompanying drawings.

Certain operations in machining very large castings are accomplished with facility by the use of a traveling head Shaper having a reciprocable tool carrying ram and in order that other operations, such as milling certain parts may be done at the same setting and thus facilitate the work, it is desirable to provide such machines with a suitable milling or boring attachment which may be quickly adjusted to any desired angle and is particularly adapted for the purpose. t

The object of this invention is to provide such an attachment andcombine the same with a holder for a shaping or planing tool in such a manner that either the rotary cutter or the fixed tool may be readily brought into operative position and adjusted to the work.

A further object is to provide certain other new and useful features in the construction and arrangement of parts, the invention consisting in the matters hereinafter set forth and more particularly pointed out in the appended claims, reference being had to the accompanying drawing in which- Figure 1 is a longitudinal vertical section through a device embodying the invention showing the same attached toa shaper ram; Fig. 2 an end elevation of the same; Fig. 3, a horizontal section on the line :v of Fig. 1; and Fig. 4, a side elevation.

The attachment embodying the invention is shown as applied to the end of a shaper ram 1 of the usual rectangular shape in cross section and having a reduced and externally screwthreaded end 2. The ram is preferably formed hollow and extending through the hollow ram is a tubular arbor 3 formed with Aa tapering seat in its end for the tapered hub or shank 4: of a bevel pinion 5, the shank of said pinion being provided with a key7 G to engage a slot in the seat and secure the .pinion and arbor to turn together, and the shank being held to its seat by a rod 7 extending through the tubular arbor and having a screwthreaded end to engage a` socket in the end of the shank.

Upon the screwthreaded end 2 of the ram 1s a split ring 8 held from turning thereon by means of a clamping bolt 9 extending through openings in ears on the ring adjacent to the point where it is split, to contract said ring, and said ring may be further held against turning by detachably securing a ciamping bar l0 to one side of the ram adjacent to the back of the ring and inserting` a tapered pin through an opening 11 in the bar into a hole provided therefor in the ring. The ring is provided with a T-slot 12 in its front face to receive the heads of a series of bolts 13 from securing a head lll to the ring. This head is formed with bearings for a transverse spindle 15 upon which is secured a bevel gear 16 in mesh with the gear 5, said head forming a casing for said bevel gear. Suitable bushings 17 and 18 are provided for the spindle and lock nuts 19 and washers 2O adjustably secure the spindle in place. An extended end 21 of the spindle is screwthreaded to receive a suitable cutter head 22, of any desired construction, the head being locked in place by lock nuts23, and this end of the spindle is also preferably formed with a tapered socket 24 indicated in dotted lines in Fig. 3, to receive any other form of tool which may be held in place by a rod 25 extending through a bore in the spindle.

In the end of the head 14: opposite that which is faced off to seat against the ring 8, is a screwthreaded opening to receive an externally screwthreaded stud or projection 26 on a suitable tool holder 27 having side flanges 2S between which is a block 29 pivotally supported upon the flanges by a pivot pin 30 and having a suitable opening to receive a cutting tool or bar 31, clamping and adjusting screws 32, 33 and 34 being provided to engage the tool and hold it in place. The stud 26 of the tool holder is prevented from turning in its opening in the head 14 by a clamping block 35 slidable in a cut-away portion or slot in the head 1st into engagement with the stud 26, said block being moved bv means of a screw 36.

The T-slot 12 in the ring 8 is concentric with the axis of the pinion 5 on the arbor 3 and thus by loosening the bolts 13, the

head'iiiay be rotated uponthe ringt'ofsvving the spindle 15 to any desired angle and when so swung it may be securely locked in the position to which it is turned by means of 5 a tapered pin passed throng-han opening?? (see Fig. 2) in the head into engagement with lany one ofa 'series ofopeiiings 68 indicated in dotted lines in the ring S. The head may therefore be quickly adjusted to set the tool carried and driven by the spindle, at any desired position radiallyfrom and at right angles to the longitudinal axis of the arbor, and by Combining a tool holder for the planing tool with the head, said tool and any'tool adapted to be' driven by the spindle 'jl' may beinterch'angeably used without the necessity for dismounting the head from the ram. The rotatable mounting of the head also provides a. rotatable adjustment vof the planingtool so that it vmay also be jset at any desired angle, and by placing the v spindle and planing tools at different 'anfgies upon thehead, one does not interfere `with 'the use of the other.

"Obviously, chan-ges may be made in the "constructionan'djarrangement offparts Without departing from the spirit of my invention and 1 do not'therefore limit myself Vto the construction shown.
